What I don't understand about this issue: why even zero velocity? There should never be zero velocity, since there is nearly always some wind, It is a classic problem in flight simulation, and simplistically a lot of the maths don't function very well at low/zero velocities. JSBSim models thi

[Flightgear-devel] New JSBSim code

2006-01-13 Thread Jon S. Berndt
As has been mentioned, the new JSBSim code has/is being moved over to FlightGear. It is JSBSim v0.9.10 code, using JSBSim config file specification v2.0. Until I get time to write some proper release notes, please see the most recent three or four JSBSim newsletters ("Back of the Envelope") on the
